A bicycle comprising a first element of the frame (10) extending from one end carrying a front wheel to a lower end (10b), a second element of the frame (20) extending to a lower end secured to the first lower end, a rear fork (8) comprising a base (32) extending from the first element to a support axis (33) and a stay (36) extending the support of axis until the second element, a bottom (40) with a plate (41), a rear wheel driven by a pinion (45) inside the fork, a belt (43) in mesh with the plate and the pinion. The base (32) has a major portion (61) arranged in a straight line (d) passing through the lower ends of the plate and the pinion. The belt runs through the triangle formed by the second element of the frame, the base and the cable, which form an assembly that cannot be dismantled.
